Project Restoration of a backwater of the Arkansas River, Rector Chute
The Rector Chute backwater will be restored to prevent conversion of aquatic habitat to terrestrial habitat through sedimentation. Select areas will be dredged with a Mudcat hydraulic dredge.

Project Restoration of Connectivity to Coal Pile, a Backwater of the Arkansas River
In order to restore connectivity to Coal Pile, the canals from the Arkansas River into Coal Pile will be dredged with a Mudcat hydraulic dredge, which was recently obtained from federal surplus equipment for use on this project.

Project Restoration of Essential Habitats for Juvenile Tarpoon and Snook
Habitat loss and degradation are major threats to coastal fisheries, especially alterations of freshwater flow into estuarine habitats. This project will restore natural topography and hydrology to 229 acres of coastal land that includes juvenile habitat for economically and recreationally important tarpon and snook. Monitoring of water quality and fishes within mangrove creeks will quantify the changes resulting from restoration. An established education program will be used to disseminate project results to the public, and the project site will be protected and managed as a public park and nature preserve in perpetuity. This project is currently on-going.

Restoration of Native Charr in Big Wadleigh Pond Maine
This project will restore 157 acres of habitat for native brook trout and arctic charr in Big Wadleigh Pond in northwest Maine by collecting eggs/brook stock from the dwindling adult populations and rearing them in a private hatchery while the pond is chemically treated to eliminate an illegal introduction of rainbow smelt. Restoration will also benefit anglers at this unique and popular fishing destination.

Restoring Aquatic Organism Passage within Wolf Laurel Branch, NC
This project will replace the existing double culverts with a bottomless structure to provide passage for brook trout and native nongame species. Replacement of these culverts will eliminate all artificial barriers within the Sand Creek drainage and reconnect existing populations of southern strain brook trout within approximately 2 miles of suitable habitat.

File Sampling strategies for estimating brook trout effective population size
The influence of sampling strategy on estimates of effective population size (Ne) from single-sample genetic methods has not been rigorously examined, though these methods are increasingly used. For headwater salmonids, spatially close kin association among age-0 individuals suggests that sampling strategy (number of individuals and location from which they are collected) will influence estimates of Ne through family representation effects. We collected age-0 brook trout by completely sampling three headwater habitat patches, and used microsatellite data and empirically parameterized simulations to test the effects of different combinations of sample size (S = 25, 50, 75, 100, 150, or 200) and number of equally-spaced sample starting locations (SL = 1, 2, 3, 4, or random) on estimates of mean family size and effective number of breeders (Nb). Both S and SL had a strong influence on estimates of mean family size and ^ Nb; however the strength of the effects varied among habitat patches that varied in family spatial distributions. The sampling strategy that resulted in an optimal balance between precise estimates of Nb and sampling effort regardless of family structure occurred with S = 75 and SL = 3. This strategy limited bias by ensuring samples contained individuals from a high proportion of available families while providing a large enough sample size for precise estimates. Because this sampling effort performed well for populations that vary in family structure, it should provide a generally applicable approach for genetic monitoring of iteroparous headwater stream fishes that have overlapping generations.

Project chemical/x-pdb St. Catherine Creek Biological Monitoring in support of Landscape Model Development
The Pvt. John Allen National Fish Hatchery, the Baton Rouge Fish and Wildlife Conservation Office and the Gulf Coast Plains/Ozark Landscape Conservation Cooperative (GCPO LCC) are partnering to develop a proactive approach in identifying problem areas and delivering aquatic habitat restoration actions, on the ground, before the problems reach an irresolvable level. This joint effort is already in the full process of data collection and evaluation to develop a spatially explicit model of aquatic habitats found on the St. Catherine Creek National Wildlife Refuge in MS. The full spectrum of biological needs for both of the alligator gar, paddlefish, and other floodplain dependent species are found in this floodplain. The existing project is already developing remote sensing capacity to characterize all aquatic habitats found in this interior floodplain in terms of the biological needs of aquatic species. In addition, data on bathymetry, water quality parameters, flood frequency and duration periods and vegetative types are being collected in order to accurately portray and verify habitat characteristics in the spatial model. Hydro acoustic and side scan imaging will be utilized in order to deliver the highest quality data available to resource managers at the present. Quantitative biological information is necessary to complete the suite of data for the model. Abundance and distribution of selected fish needs to be collected in conjunction with environmental data in order to adequately characterize the importance of various physicochemical conditions to aquatic life. This project will collect those data on St Catherine Creek NMR. This project is currently on-going.
